    Notes: Rapid technological advancements have contributed to the increasing application of adhesives. Because of these accomplishments, because of continuing materials research and process development activities, and because of their inherent advantages, adhesives have a great potential for the future. Requirements for the future impose a severe challenge on developmental capabilities. More severe structural requirements and environmental conditions may be expected. Because of increasing complexity and costs, there are requirements for significantly higher orders of reliability and lower fabrication costs. Improvements in bonding processes and development of comparatively new techniques are desirable. Test methods require further development and standardization - especially nondestructive methods. Continuing work in collecting and reporting pertinent information, especially on properties and design parameters for adhesive bonding is helping to advance the utilization of adhesives. Current trends indicate that adhesives are progressing from the realm of “art” to science, a factor which should substantially aid in advancing the future potential for adhesives.

    Notes: The rate of consumption of oxygen by cotton and cottom cellulose from solutions of hypochlorite in the pH range 5-10 has been studied. Kinetic plots were obtained either by periodically titrating aliquots or by automatically recording the amount of alkali required to keep the pH constant. In the case of pure cotton cellulose the plots are linear, whereas in the case of cotton the plots consist of two parts, an initial, rapid oxidation of the impurities followed by a slower, linear oxidation of the cellulose. The dependence of the rate of oxidation on the pH may be expressed by: \documentclass{article}\pagestyle{empty}\begin{document}$$ {{ - dC} \mathord{\left/ {\vphantom {{ - dC} {dt}}} \right. \kern-\nulldelimiterspace} {dt}} = kC^2 _{{\rm HOCl}} C^{{1 \mathord{\left/ {\vphantom {1 2}} \right. \kern-\nulldelimiterspace} 2}} _{{\rm ClO - }}$$\end{document} which also accounts for the dependence of the rate on the initial concentration of oxidant. A mechanism is suggested in terms of the free-radical OH and Cl2OOH.

    Notes: Functional groups and degradation of cotton oxidized by hypochlorite at several pH values in the range 5-10 were studied. The carboxyl group content of the oxidized cottons increases, while the aldehyde and ketone group contents decrease with increase in pH. Approximately 40% of the oxidant consumed is accounted for by the functional groups at all pH values. The ratio of carboxyl, aldehyde, and ketone groups formed per scission is 1-1.5:3:3.5 at the acidic pH range and 5:0.8:0.0 at pH 10. Oxygen consumption per scission is 26 atoms, out of which 10.4 atoms are accounted for by the functional groups. The rest of the oxygen is explained by oxidation of the soluble products of the short chain material in the fiber phase and by the functional groups of the short chains with D.P. up to 37. The degradation was found to be random at the whole pH range studied, as proved by the ratio of the number-average and weight-average molecular weights and by the linearity of the plot of log [η] vs. log (Oc + Oc0) where Oc is the oxygen consumed and Oco a constant. It is suggested that the degradation and oxidation reactions occur simultaneously and, at a given pH, with similar rates, so that all carbon atoms of an anhydroglucose unit in all chains of the amorphous phase will have a similar probability of being attacked.
